What is the significance of ground control points to the map to be geo-referenced?

Ground Control Points, which are commonly referred to as "GCPs", allow images to be georeferenced to a higher degree of accuracy. Ground control points are locations on the earth which have been accurately surveyed for both their elevation and GPS location. Without these control points an images georeferencing is based solely off of the data from positioning hardware aboard the imager and a sensor model. In addition to the increased accuracy obtained by using GCPs, a Digital Elevation Model (DEM) should be used so that you correct for elevation errors.

Is it normal to have a 220 volts from line to ground?
In England and Europe yes, 240 volts is the star point voltage of a 416 volt three phase four wire system. In North America no, it is not normal to have 240 volts to ground. On a single phase system that is used in homes it should only be 120 volts. In control panels that use 240 volts as a control voltage and one side of the control transformer is taken to ground, only then would you find the 240 to ground. This connection is used to trouble shoot the control panel by allowing one of the voltage tester leads to be connected to ground while the other lead can be used to probe for voltages at terminal points.
